Preheat oven to 300 degrees and spray a nonstick baking sheet with cooking spray. Mix the sugar and spices together in a small bowl. Beat the egg white lightly with a fork in a larger bowl; toss the pecans and stir to coat. Sprinkle with the spice mixture and coat pecans evenly. Using your fingers, lift the pecans, one by one out of the bowl and transfer to a baking sheet, separating them. Discard any leftover sugar/egg mix. Bake 30 to 35 minutes. Cool for a few minutes and transfer to another baking sheet, breaking pecans apart as necessary; let cook completely. Keep covered in a dry place for up to 5 days.
